To all whom z't may concern: Y

' Be it known 'that I, HARRY S. HART, a citizen ofthe United States, 1 in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Cars, of whichthe following is a specification.

This invention relates to freight cars ofthe type commonly known .as hopper cars,

which are used very lar ely for ,the'transf -portation of coal or the li es dumpablemate-- rial, and has among its objects the limprove# ment of th1s type of carin a manner` to greatly increase the load carrying capacity of the car without `changing its` overall dimensions, and to providesu'ch a'car'from -th'e car being practically self clearing.

scribed in the following'` specification and claims. The invention is illustrated on the accompanying sheets of drawings, in vwhich-4 j Figure 1 is alongitudinal sectional v'1ew l with my invention;

of a dump car -constructed accordance ig. 2 is a transverse sectiongl-viewof the, fsame dump car taken overithe trucks; and

Fig. 3 is another transverse sectional vview of the same dump car taken intermediate the trucks. E" 1,

It has been customary to' build hopper cars 'for'thetransportation of coal, an d the trucks vdischarging the load throughthe center. of the car by meas;s of cross hoppers' or longitudinal hoppers provided'with suitwell known and require no partlcular 'de-l scription for an understanding 'thereof. Owing tothe location of the inclmed end portions lover the trucks, those portlons of the cars at the endsare largelyuseless for load carrying, so "that" any attempt' to increase the capacity of these cars necearily has been by lengthenin the car orby irl- -creasin its height,'whi e the dischar e of the loa through the car hoppers is di cult,

residing at Chicago.

1ke comvmoditles, havmginclined end portionsfor even where speci-al unloading stations are provided owing to the necessarily'restricted door opening provided in the cross hoppers.

vWhile longitudinalhoppers also have been provided in cars of this type for discharging the load at the sides in a-'manner to make the unloading easier, attemptsto apply this principle to the car have resulted in a greatly decreased load carrying capacity.

By my present invention I overcome jthe difiiculties heretofore experienced in this type of car, making it 'possible to carry in a car-ofthe same length a greatly increased load, and -at-thesame time making it possible to'v discharge-the load at ya greatly Vreduced expenditure of time and labor. which the load may be more quickly dis-f' charged with a minimum amountof labor,

he bodyio of this dump car, whieh is carried. upon'trucks including wheels ll'at each y Y l end ofthe car,v comprises sides 12, ends 13, W ith these and other objects, which hereinafter will be.y pointed out, the'- invention consists of the combinations and details de` portions 418'extending from a point adjacent wardly, and foutwardly sloping stationary and-over thecenter sill 20 toward the sides of tho-,ca l.'. The door intermediate the trucks, includes stationary portions 21 which eX- tend downwardly and inwardly from the lower edgesof the car sides 12 toward the 'center f the car, said stationary .portions 21 extendlng to a -pomt and generally being locatedlower than the stationary floor portions 18 over the trucks. Cooperating with the stationary floor portions 21 are dump doors 22 which preferably are p'ivotally connected to the center sill construction and extend downwardly and outwardly therefrom "to a point' where they meet the lower edges of the statlonary lioor portions 21, therebeing in effect therefore substantially two longitudinal hopper portions'intermediate the trucks, one on each side of the center sill. ln order that the car may be selfclearing in un- -loading I have shown in the present embodiment of my inventionthe stationary floor Sections 18 over the trucks extending upwardly toa point overthe center sill to foi-1n' an A-shaped apex 15 as a continuation of the floor sections. The upper and lower floor sections at the ends and the floor sections intermediate the same of the car respectively, may be connected by Hoor members 17 slop- Suitable means may be provided for closing the space between the outer edges of the sloping floor portions 18 over the truck and the sides of the car, through which space the load over the trucks is dumped. In the present embodiment of my invention I- 'have shown side dumpl doors 19, which are pivotally connected at the lowei` edges of the sides 12, and extend downwardly and inwardly with respectto the center of the car Ato meet the outer edges of the A-shaped floor portions 18. Any suitable operating mechanism may be provided for operating the dump doors 19. Likewise any suitable operating mechanism may be employed for operating the dump doors 22.

By thus providing a car having stationary floor portions' throughout the whole length of the car, that is stationary floor portions over the trucks and with downwardly and inwardly extendil'lg floor portions intermediate the trucks, and dump doors lpivotally connected to the center sill construction an'd meeting the lower edges of the stationary floor sections 21 intermediate the trucks, I

am enabled to provide a hopper. car, thel ca r ving capacity ofI which is greatly Vinc ed for' any given length, width and Hheight, at the same time making the car' self cleaning, owing to the arrangement ofthe inclined `surfaces inthe car 1n reference to the dumping doors.`

A if'sstat'ed'before, the dumping means at the'ends of the car over the trucks isat a higher level than thedumping means inter-4 mediate the. trucks, and the load over the trucks is dumped outwardly and the load intermediate the trucks is dumped inwardly. lVhile the floor over the ,trucks is composed of fixed A-portions, a portion of the fioor between the trucks including the dump doors 22 forms a movable A-portion at a lower level from those ofthe A-portions over the trucks. f

It. is my intention to cover all modifications-of the invention falling within -the spirit and scope of the following claims.

What I claim is: l. A car of the class described having sides, ends vand a floor, the fioor portion over the trucksl,being A-shaped and adapted to discharge the load outwardly toward the sides of the car, the floor between the trucks including doors, said doors extending downwardly and outwardly toward the sides of the car.

2. A car of the class described having sides, ends and a Hoor', the floor portion over the trucks being A-shaped and adapted to- 'LessinesV and doors extending from the center of the car toward the fixed floor portion between the trucks.

ll. A car of the class described having sides, ends, and a floor extending from end to end of the car, the fioor over the trucks being composed of fixed A-portions and be- ,t-weenthe trucks of an 'A-portion having movable inner sides at a diiierent level from those of the A-portions over the trucks.4

5. `A car of the class ydescribed having sides, ends, and a floor extending from end to end of the car, the* floor-overthe trucks being composedV of fixed A-portions and between the trucks of an A-portion having movable inner sides at a lower level than those of the A-portions over the trucks.

6. A 'car of the class described having sides, ends, and a floor including fixed A- i portions over the trucks and fixed portions intermediate the trucks extending down- .wardly and inwardly from the sides of the car, and doors associated with each of said fixed floor portions, the doors between the. trucks extending downwardly and' outwardly frointhe center of the car.

T.AV car of the classdescribed having sides. ends, and a floor including fixed A- portions over the trucks and fixed portions intermediate the trucks extending downwardly and inwardlyfrom the sides of the ca'r, and doors associated' with each of the saidfixed floor portions.`

8.'A car of the class described having sides, ends, and a floor including fixed' A- portions over the-trucks, an independent floor intermediate the trucks including a plurality of hoppers dumping inwardly;

9. A car of the class described having sides and ends, the floor over the trucks cornprising portions sloping downwardly and outwardly toward the sides of thecar,l outwardly swinging doors pivoted to the sides of the car coperating with said stationary fioor portion-s, the floor between the trucks comprising downwardly-and inwardly vextending stationary portions,v and inwardly swinging doors pivoted adjacent the center sill cooperating with said downwardly and inwardly extending floor portions.
